Copper tubing?

Hi all,

I am on the hunt for a certain form of copper tubing and having
trouble finding it. I am looking for copper tubing that has
about a quarter inch diameter and is the hard tempered staight
stock. I have looked at all my local hardwares,plumbing suppliers
and refrigeration suppliers. The only straight stock they carry
is a half inch and up. They have the quarter inch but it is the
soft coiled tubing. I know it exists because I have some that was
given to me but have no idea where it came from. I have tried
contacting a couple of tubing manufacturing companies that I
found on the web with no response yet. I’m assuming they probably
only sell in large amounts. Any ideas? Thanks for your
help!-Carrie Nunes @tnunes

Hi Carrie,

You might try hobby/model shops, if you haven’t already. They
often have different types of metal stock in copper, brass and
aluminum.

Twelve inch lenghts of brass and copper tubing of many widths
can often be found in hobby stores that carry supplies for
minature train devotees.

How about drawing it down fron 5/16 soft tubing. It should get
pretty hard and if you are careful it should be straight. dave

G’day; I have bought straight thin wall telescoping brass
tubing in several diameters up to 1/2" here in NZ, but I expect
your model shops aren’t much different from ours - they probably
get it from America anyway! But it is very useful, for it is
reasonably soft and can be fairly easily drawn down to smaller
sizes - drill a hole in a bit of 1/8th steel plate, polish the
edges with a bit of abrasive paper over a tapered stick and
you’ve got a tube drawing die - crude but useable. Anneal the
brass if it doesn’t draw easily enough. I have a length of
about 3mm dia tube fastened to my sawframe, and bent so it
points down at the work. I attach an old El Cheepo aquarium pump
to it with a length of very flexible 3mm rubber tubing - and
there you go; your saw-line is constantly visible as you cut,
especially if you use a black marker pen background for your
scribed line to show against. –

Hi,

Try a catalog called Small parts- 1 800 220 4242. They have
tubing also many other odd items, small bolts, some tools,
telescoping tubing,and much misc.

Hope it helps.

I’ve found copper and brass tubing at my local hardware store.
I think some of it is used for plumbing.

Our hardware stores carry anything from very tiny (could be used
to make converters for brooches- converting to necklaces) just
large enough to fit over a pin, to several inches in diameter.
(Ace Hardware and True Value) the tubes precut to about a foot
long. There are also various diameters of brass and copper wire
in the same area. I’ve bought these (various diamerters) for
between $.75 and $1.50 per foot.
